Zoomable User Interface for Hierarchical Presentation Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional slide show presentation tools require high user input for navigation, are visually inappropriate for professional settings, and limit flexibility in reusing presentations across different audiences and situations, as they rely on linear sequences and traditional GUI features.
Innovation Solution
A zoomable user interface (ZUI) system that organizes presentation information hierarchically, allowing users to navigate through slides and text labels by panning and zooming, with automatic path updates based on modifications, enabling flexible navigation and presentation customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional GUI features (scrollable lists, grids, hyperlinks) are used for navigation, then the interface can be operated with standard workstation features, but the precision and attention required for navigation increases and professional appearance is compromised
Solution Approach 1:
The patent transitions from traditional two-dimensional GUI navigation (lists, grids) to a three-dimensional zoomable space where slides are arranged in hierarchical levels. Users navigate by zooming in/out and panning, converting linear/planar navigation into spatial navigation that reduces pointing precision requirements while maintaining ease of operation.
Solution Approach 2:
The presentation structure is segmented into hierarchical levels (parent slides and child slides) that can be independently navigated. This segmentation allows users to jump between different levels of detail without traversing every slide linearly, reducing the precision needed for navigation while maintaining comprehensive access to content.
2Device complexity
If a linear sequence of slides is used for presentation, then the presentation structure is simple, but the flexibility to return to previous subjects or search specific information is limited
Solution Approach 1:
The patent implements a nested hierarchical structure where child slides are contained within parent slides. This nesting allows users to zoom into specific topics for detailed exploration and then zoom out to return to broader contexts, providing flexible navigation while maintaining a relatively simple overall presentation structure.
Solution Approach 2:
The presentation structure transitions from a static linear sequence to a dynamic hierarchical tree that can be explored in multiple directions. Users can dynamically navigate between parent and child slides, adjust the level of detail, and reposition themselves in the presentation flow based on their needs, significantly enhancing navigation flexibility.
3Adaptability or versatility
If manual hierarchy creation is required for slide organization, then the presentation can be adapted for different audiences, but the time and effort required for setup increases
Solution Approach 1:
The patent performs preliminary organization of slides into hierarchical structures during the presentation setup phase. By pre-establishing parent-child relationships and hierarchical levels, the system enables rapid adaptation to different audiences during actual presentation without requiring manual reorganization, thus reducing setup time while maintaining adaptability.
Solution Approach 2:
The hierarchical structure serves itself by automatically organizing slides based on their content relationships and allowing users to navigate the presentation through intuitive zooming and panning operations. This self-organizing capability eliminates the need for manual hierarchy creation during presentation adaptation, reducing setup time while maintaining versatility.

AI summary
Methods and systems for supporting presentation using a zoomable space. In an exemplary method, a structure, such as a hierarchy, of presentation information is provided. The presentation information may include slides, text labels and graphical elements. The presentation information is laid out in the zoomable space based on the structure. A path may be created based on the hierarchy and may be a sequence of the presentation information for the slide show. When a modification is received in at least one of the hierarchy and the layout, the path may be automatically updated based on the modification. During a presentation, the presentation information is displayed based on the path.
